While this is typical for the United States, other countries may use a different format for dates. Those formats are fine. Atypical doesn't mean not allowed.

Additionally, what do you think of the narrative content, not just the small grammar and mechanics nitpicks? If you only comment on small details, it may give the author the incorrect impression that everything else in the draft is fine and not in need of fixing. Misleading feedback can result in an author getting the wrong impression of their work, and may lead to them posting a page that is not yet ready for the mainsite, and then getting slammed with a bunch of downvotes that they don't expect.

If you're not inclined to write more of a substantial review, please hold off on making the first post so a more experienced reviewer can address the thread first. As staff reviewers prioritize threads with no replies, someone posting a low-content critique actually can make it harder for the author to get a more thorough review.
